Abstract (en)
[origin: WO2022258886A2] Various example embodiments relate to providing audio or haptic feedback to a user. An apparatus may comprise: detection circuitry coupled to a first coil, wherein the detection circuitry is configured to detect a user input on a surface based on a triggering signal comprising voltage or current induced at the first coil by displacement of the surface by a user. The apparatus may further comprise feedback circuitry coupled to a second coil, wherein the feedback circuitryis configured to activate a feedback signal in response to detection of the user input by the detection circuitry, and wherein the second coil is configured to cause or alter movement of the surface based on a magnetic field configured to be generated by the second coil upon activation of the feedback signal. Apparatuses, methods, and computer programs are disclosed.
